Question Game freezing and fps drops

Sep 26, 2020
Hey. I'm not really sure if this is in the right section and I apologise if it's not. I'm stuck with a issue and frankly to say, I'm totally clueless what to do next.
My laptop is an Acer Nitro 5 2019 edition, RX 560X 4gb, 16GB DDR4 ram and Ryzen 5 3500H. Every game I play starts off well and then this random fps drops starts for no reason. I always play with charger connected, keep all background tasks apps closed and I've never had this issue before. I've played low graphics game such as Euro truck simulator 2 and prototype 2 which I had absolutely no trouble running before but it lags in low setting as well. I've cleaned the dust off the GPU, the fans and the exhausts as well, messed around with every setting or change in registry editor, clean installed the windows (1903 btw) , reinstalled and reverted back to old drivers and still nothing. I was hoping someone out here can help me out and thanks in advance.
